Which of the following statements about the combustion of glucose with oxygen to form water and carbon dioxide (c6h12o6 + 6 o2 → 6 co2 + 6 h2o) is correct?
(a)- the reverse reaction, making glucose from water and carbon dioxide, must be an exergonic reaction.
(b)-this is the process of cellular respiration, an anabolic pathway that releases free energy.
(c)-the free energy lost in this combustion is less than the energy that appears as heat.
(d)-the entropy of the universe decreases as the result of this reaction.
(e)-the entropy of the products is greater than the entropy of the reactants.

Dying the folding patterns of protein molecules can microbiologists better understand cellular processes as well as some diseases, such as alzheimer’s, that are caused by proteins that have misfolded. the folding of these complicated molecules can be simulated on computers, but it takes a lot of processor power and time for even expensive supercomputers to do this. a group of researchers at stanford university developed software that can be used to distribute the processing of data to anyone who is willing to donate time on their idle personal computers. as a result, the researchers have been able to achieve protein-folding simulations that are far better than those other computing methods have done. which statement best describes the work of these researchers? the work is not scientific because the data are not processed in one location. the work is not scientific because the simulations are not reproducible. the researchers applied creativity to solve a problem in running an experiment. the researchers used only well-established scientific techniques.

If a molecule with a molecular formula of c13h18 is treated with an excess of h2 in the presence of finally divided pt metal under conditions required for maximum hydrogenation of the molecule to give a molecule with a formula c13h24, how many rings are in the molecule?
